HUMIDIFYING' AND AIR-CONDITIONING APPARATUS.

' Specification of Letters Patent.

Patented March 9, 1909 Application filed April 1, 1907. Serial No.-f365,727.

. midifying and Air-Conditionin Apparatus;

and I do hereby declare the fo lowing to be a full, clear, and exact description of the invention, such as will enable others skilled.

in the art to which it appertains to make and use the same.

. shown broken.

My invention relates to huinidifying, and air conditioning apparatus, has for its object furtherdevelopments in the device,

shown and described in my applicatidn for a patent, Serial No. 312,453, and consists in certain im rovements in construction which u will be ful y-disclosed in the following speci- 20 fication and claims.

In the accompanying drawings, which .form part of .thiss ecification;-Figure 1 represents a side eevation of a duplex humidifier embodying my invention, with art of the elongated horizontal extension broken oif.v Fig. 2 a vertical longitudinal section of the same, the extensions being Fig; 3 a like View. of a humidifier having a single spray-head. Fig. 4 a. like view of a humidifier having-two spray-heads in one casing and one horizontal extension. Fig. 5 an end elevationhl ig '6 a vertical transverse section on line 6, 6,

Fig.1. Fig. 7 a like view on line 7, 7, of the same, figure. Fig. 8 a side elevation of a modifiedconstruction including. means for I sulpplying air from outside the building, and

eating coil. Fig. 9 avertical longitudinal section of the same. Fig. 10 an end elevation. Fig. 11 a vertical transverse section on line 11, 11, on Figs.8 and 9, and Fig.12

a like view on line 12,12 on the same figures.

Reference being had to the drawings and the designating characters thereon, the nume'ral 1 indicates a head or central portion of the casing, which in the. duplex humidifier is provided with primary branches or extensions 2, 2, one on each side of the head 1, and with supplemental elongated horizontal extensions 3, 3, while in the single humidifier only one primary extension 2,

and one supplemental extension 3 are used.

4 indicates a fan propeller which may be driven by an electric motor 5, or by any other preferred means and sup lies air from the room in which the humidi er is located,

located, and in which cham through theopen top 6 of the head of the casing, and on which the fan and the motor rest, i1rthe-construction of the duplex humidifier. I

7 indicates a double walled deflector under the fan for directing the air toward each end of the casing.

8 are spray-heads for supplying water in the form of finely attenuated spray, or aqueousvapor, supplied in the usual mane ner throughpipe 9, and branch 10, on which the spray-head is supported.

a 11 indicates an annular deflector having acorrugated wall against which the spray from the spray-head is rojectedwith such force as to cause the fine y attenuated particles of water to be deflected and further broken u The deflector is concentrically supporter in the casing on suitable stays 12 properly secured to the wall of the casing, forming an annular chamber 11 around the Y deflector.

Within the casin -is a spray chamber 13 for-each extension o the casing, and in which the deflector ;11 and the spray-head 8 are er the air passing through the casing receives its initial dousing orsaturation with water. supplied by the spray-head. I

14 is a grate preferably of cypress-wood, the

bars of Which form'a plurality of collecting and evaporative bodies or surfaces 15 against which the saturated air im inges for condensing and extracting surp us water from. the air and for the further saturation of the air before it issues from the humidifier. The collectin and evaporating bodies may be placed int ieend of the corrugated deflector '11', as shown in Figs. 2, 3 and 4, or they may be placed beyond the deflectors at the end of the primary extension 3 of the casing, as shown in Fig. 9, or they may be placed at any-desired point throughout the casing of the'humidifier.

16 is a door in the side of the head 1 of the casing to afford access to the interior thereof and the su )plemental extension 3 is provided with 1n cs 17 on one side which are secured to the ongitudinal drip pan 18, and the opposite side of the casing rests upon supports 19. The hinging of this section of the casing aflords ready means for raising the section for removing dust and lint which is collected as it is extracted from the air by thecleansing and purifying action of the humidifier. Surplus water is conducted from the drip pan 18 by a pipe 20, and the whole apparatus is supported on rods 21, or in any preferred manner.

The'supplemental -extensionz3 is preferably inclined or tapered on its-top toward the end of the extension, and the interior of said extension forms a collecting and condensing In the sin le humidifiers, the head 1 may i be dispense with and the fan 4 and the motor 5 secured to the end of the primary extension 3, as shown in Figs. 3 and 4.

23 isa steam coll for heatlng an as it comes from outside the building through the fresh airduct 24 in the winter, '25 a strap for supportin the steam coil, 26 apipe for supplying the coi 23 with steam.

27 is a drip pipe for taking the water of condensation out of the steam coil 23 and is provided with a valve'28 of the Well known type for automatically discharging the water of condensation as fast as itcollects.

29 are electric wires leading to the motor.- 30 are cast iron rings set in the wall 31, and through which the'fresh air duct or pipe 24 extends and connects the extension 32 of the casin of the humidifier with'the outside air.

The .iresh air duct is turned downward to keep-out rain and is also providedjwith a screen 33 toprevent birds nesting in the casing.

34 is an air mixin sion 32, provided with a sliding damper 35 which is raised and lowered by a rod 36 to j admit a greater or less quantity of fresh air as maydesired. On each side of the extension 32 are damper doors 37, also connected tothe rod '36 by arms 38 pivoted at 39 and also connected to the doors at 40, and are provided with hinges 41 at their upper ends connecting them with the top of the extension 32. By referringto the sectional views it will be seen that Fig. 11 shows the side dampers37 open and the end or sliding damper 35 closed, thus admitting air from the lnside of the room only to the casing. Fig. 12 shows the side dampers 37 closed and the damper 35 drawn down or open to its full extent, thereby admitting air to the casing only from outside the building. Byprop erly manipulating the dampers 35 and the dampers'37, 37, air may be drawn into the chamber in the exten-- casing exclusively from the inside or the outside of thebuilding or the air may be drawn from both sources of supply to furnish the propeller fan as may be desired.

42 are grooves in which the sliding damper 35 slides up and down in theextension 32 of the casing.

43 is a sheet metal incline in the end of the drip an 18, 44 a pail used for cleaning out the dim pan, and may be suspended on a hook 45.

' The extension 3 is thrown up to one side on its hinges 17 for cleanin purposes, as shown in dotted lines in Fi 10,1ihus affording ample space for the intro u'ctio of a mop to clean out the lint,dust and. other solid bodies drawn into the casing by the ropeller fan.

46 are sheet metal c ips for supporting the grate 14.

' The term spray-chamber refers to that partof the casing 1n which the air is mixed or saturated with spray, and the term collecting and condensing chamber refers to that part withinthe casing where the coarse s ray is eithercondensed by a plurality of co ectin and condensing bodies, or by contact wit! the Wall of the extension 3 of the casing on which the-coarse spray collects and gravitates intothe drip pan.

Having thus fully described my invention, what I claim is 1. In a humidifier, a casing, a spra chamber withinthe casing, an elongated orizontal extension of the. casingforming a condensing and collecting chamber, means forsupplying air to the casing, means for supplymg spray to the air as t passes through the casing, condensing and evaporative bodies arranged in the path of the-saturated air, and a drip pan on which said horizontal extension is removably supported.

2. In a humidifier, an elongated horizontal casing provided witha spray chamber, an extension of the casing forming a condensing and collecting chamber, a spray-head concentrically arranged in the spray chamber, a propeller fan, and a drip an on which said extension of the casing is removably supported.-

In testimony whereof I ailix my signature, in presence of two witnesses.
